Imaizumi Sensei began his Aikido career in April of 1959 while a student at Waseda University in Tokyo. Waseda was a 15-minute walk from the Aikikai Honbu dojo, and on May 1st, Sensei saw an Aikido demonstration by Morihei Ueshiba (O-Sensei, the founder of Aikido) and started studying aikido shortly thereafter. In 1965, with a rank of sandan, Sensei Imaizumi became an apprentice to the teaching staff (shidoin) at the Honbu dojo and his career as a professional Aikido instructor began. During this period he frequently took ukemi for O-Sensei during the early morning Aikido classes when O-Sensei would demonstrate and teach. After O-Sensei's death in April of 1969, Imaizumi-Sensei was chosen to accompany Waka-Sensei (the son of O-sensei) and his wife to enshrine the remains of O-Sensei at the Ueshiba family graveyard at Tanabe.
Imaizumi Sensei was an instructor at the Aikikai Honbu until 1974 when he joined Koichi Tohei Sensei in his new organization, the Ki-no-kenkyukai (Ki Society; Shin-Shin Toitsu Aikido). In July 1975, Imaizumi Sensei came to New York to found the New York Ki Society and assume the role of Chief Instructor for the Eastern Region and the US. In September of 1987, he resigned from the Ki Society. Shin-Budo Kai was founded in October 1988. Imaizumi sensei continues to follow the teachings he received from O-Sensei, while developing and offering his own perspectives on technique, form and philosophy.
